Many of these signals were heard for several hours, making the difference even more striking. the wild west of 6m.ĭuring one particularly noteworthy period of no action in the lower part of the band, JT65 signals were either copied or exchanged with CO8, V31, TG9, KP4 and XE. the one spot in the conventional mode section of the band where anything goes. In this respect, the JT65 segment is like a wider version of the 50.125MHz calling frequency. things can get messy pretty fast when the JT65 band fills-up with S9+ signals! Under these conditions, moving well away from the crowd is often better than trying to fight overlapping signals, often made worse by S9++ signals in your own grid, transmitting on the opposite sequence. When the band really opens up however, things are different. This is when JT65 really shines as it is primarily a weak-signal mode. Perhaps this alone explains why I see such a difference between the two segments of the band. There is no doubt that JT65's ability to dig deep into the atmospheric band noise and decode signals too weak to be heard on CW, provides an advantage when conditions are marginal. This summer, there appears to be much more interest in 6m JT65 than ever before, as I see many familiar CW operators up the band on digital. Thursday morning was a good example, with several contacts down into the southeastern 'EM' grids on JT mode while seeing no reports of similar contacts being made on CW or SSB from my region. On several occasions this week, I have heard or worked dozens of others on JT mode while the bottom end of the band appears void of signals. My main interest has always been CW but for some reason, and much to my surprise, the small sliver of JT spectrum space above 50.276MHz seems to be much 'busier' than the lower end of the band!

You can read more about the features of JTDX and how to get started with it via the link that follows.This past week, most of my 6m time has been spent monitoring or working JT65A mode stations, up the band a bit from my usual hangout around 50.100MHz. With all features enabled, JTDX seems to decode more signals on a crowded band than WSJT-X. These features can be selectively enabled to match band and signal conditions as well as the user’s available CPU horsepower.

The JTDX software adds a number of FT8 decoding options that are useful on crowded bands and in situations when signals are very weak. It appears to have most of the features of the current version of WSJT-X with the notable exception of support for specific contest exchanges. The software is derived from WSJT-X and we’ve been using it here for DX’ing and for weak signal FT8 work on 6 meters. The feature additions definitely provide some useful enhancements. We’ve been testing JTDX V2.0 release candidates here for about a month now.
